Deregistering a phone you can't find

I have more than the number of phones that my base will control. A couple of these have been lost or discharged, so I can't deregister them in order to register the valid "extras" that I have laying around. The base won't deregister them if it can't "find" them. thanks dottye

Re: Deregistering a phone you can't find

I had trouble deregistering one of the phones, as it has to be close to the original base (kept telling me out of range). I found out that pressing END and #, also deregisters.

I bought 2 sets of the uniden DECT 1480-3. I want 6 handsets to work with one base. How do I add 3 handsets to a base that already has 3 handsets?

The only logical way is to get the additional handsets to communicate with the base. And to do that you must set them to the frequency of the base. You Use guide will tell you how to set the frequency n the handsets to talk to the base. They way you set the original ones.
BUT, I doubt if this will work. Why? Because if that was the case if you and I had the same company phones, then I would stand outside your home and set the same frequency on my handset and misuse your phone. A great security risk in today's world. But there is no harm trying it out. Just set the same frequency on the additional ones as the base. If it works, then you will have that many more intercoms too. And do let me know if it works.

Our phones keep saying searching, but nothing happens. We tried deregistering the phones and registering again, but it doesn't work. We tried unplugging everything and plugging it in again, but still...

It's likely that the transmitter located in the base station has failed. Your handsets are looking for an answer from that station and not receiving any.
If not still under warranty, it may cost less to replace the whole system than repair the base station even though most of the electronics that makes the system 'cordless' is mostly dependent on a packaged RF module that costs only a few dollars wholesale.

My uniden phone says - out of range

Uniden wxi477 out of range fix

This problem arises when the handset does not communicate with the base.
These are the steps:
1: Deregistering the handset
2: Registering the handset to base

Deregestering clears the stored (incorrect) base information on the handset.
Reregestering allows the base to assign a new ID for the handset.

Deregistering- press and hold the OFF (red button) and the # button on the handset for 5 seconds. select base unavailable and press OK. Are you sure appears. select yes and press OK. you will hear a confirmation tone. The handset will delete its own base information without trying to contact the base. It will now display MODELS VARY PLACE HANDSET ON THE BASE FOR REGISTRATION.

Registering the handset with the base- Make sure the tel. line and power is plugged into the base.
Press an hold the register button under the base (located between the tel. line and yellow power socket under the base) for 5 seconds until the red light flashes. At the same time press and hold the # button on the handset for 5 secs. You will hear a tone and It will now display REGISTRATION COMPLETE.

If it says registration failed: Retry the registration steps. Make sure the handset have enough battery power. If not charge for 15-20 hrs.
Check your connections on the base and make it is getting power.

The Steps above was my fix for the uniden wxi477 out of range problem.

Good luck.

I have a Pansonic kx-tga270s that is registered to a base I do not have. Is there a way to deregister it.

you dont need to deregister it if you have not registered all 8 hand sets with your base unit. Just register the new one and the base will assign a new # for this new. I you had registered 8 hand sets with your base already, you need to remove(deregister0 one handset from your base(it can take only upt 8).
If it still not registering please deregister as follows:
on the base unit, press program, them mute, then enter 335#, then enter the handset number you wish to deregister.
after deregistering try to register your new hand set.

Phone says ''Welcome ... please wait'' when you try to use it


I tried to copy and paste the solution for this issue, but Fixya only allows so many charecters and I guess the answer is too long.
Go to

and select the owner's manual for your model phone. Follow the procedures for deregistering the handsets and then resetting the base. then re-register the handsets and you should be good to go. It is all pretty easy, just a little to wordy for this forum I guess.

The hand set unit has a lot of static.

Try DeRegistering and ReRegistering the handset:
From the base system:
  • Press Menu
  • Scroll to System Settings - press select
  • Enter System PIN - press select (default pin is 0000)
  • Scroll to Mobile Deregustration - press ok
  • Scroll to the corresponding intercom # - press select
Then turn on Handset:
  • Please Register will be displayed - press ok or Register
  • Enter System PIN - press ok
At Base:
  • Press Menu
  • Scroll to System Settings - press select
  • Enter System PIN - press select
Back to the Handset:
  • When Select Intercom Number is displayed, select the number - press ok
Hope this helps!

I have a panasonic phone model number KX-TG6022B and wheather the phone is on the base or not, it says line in use. The line isn't in use though. I've tried unplugging both phones from the base and wait,...

sounds simple
3 things to look at

lets start with obvious i hope you have manual for phone still cause typen instructions for deregistering phone is long type
the reason phone could be showing its still in use is because phone needs to be deregistered and then reregistered back on the hand set base

the other thing is one of your neighbors has tapped your phone line giving you this busy signal

or say you still using dial up on your comp this will show a busy signal cause its using your phone line to get online
